Question

What is iron sulphate + copper

Answer 1

Reaction of Iron Sulphate and Copper:

FeSO4(sq) + Cu(s)==========>No reaction

This is because copper is less reactive when compared to iron and can't displace it from its solution

But a converse reaction like this can happen,

Fe + CuSO4==========>FeSO4 + Cu

Here,Iron displaces copper

The colour of the solution changes to green and further a reddish brown residue is accumulated on iron particles
